How to Play Rock, Paper, Scissor with Facebook LIKE

Rock, paper scissors is traditional game with a long history. I believe that our ancestors, not long after learning to walk on two feet, were using their newly free hands to do many new and interesting things such as playing this game. At that time, neither paper nor scissors had been invented yet, so the combatants would resolve to see whose rock was harder by means of smashing it into their companion’s skull.
